A few design tips about coilguns:
As far as coil composition goes the only real considerations are desired weight of the gun and the desired weight of the projectile.
Materials that have worked well for me are zirconium copper (jack of all trades), vanadium chromium steel (for REDICULOUSLY heavy projectiles), magnesium (excellent for light weight, cheap, low power guns), osmium and maraging steel.
For armature composition the best two options are Iron and Magnetic Metal Glass, nothing else can really compete with those two.
Pay attention to the diagram, you want the red line to have the highest number possible and for the green line to come as close as possible without going over.
Deal with barrel yield strength issues by first widening the bore, and then optimizing the coil. This will save you so many headdaches trust me.

Iron is pretty crap, but it's also the cheapest option functional option as armature for the coilgun.
Magnetic Metal Glass is insanely good for making smaller coilgun while having stupid high projectile velocity but it's stupid expensive.

For rail-gun and Coil-gun materials I try to look for high stiffness/strength and good strength/density. So far Amorphous carbon is my favorite for coil-guns and Aluminum Zinc Magnesium for Rail-guns. Rail guns work best with light shells pushing an even lighter payload. Meanwhile a given coil-gun design can be scaled up to support any shell mass, and payloads always hurt muzzle velocity.

Railgun and Coilgun are just, incredibly situational. For laser, you can just pump in more power and increase the aperture after you got everything right. Railgun is almost on the same logic, but they can only shoot light weight projectile as they get WAY heavier when firing heavy projectile. Coilgun is... just plain difficult to design. But we could suggest good barrel material for making railgun and coilgun. Like both railgun and coilgun can use zirconium copper and vanadium something steel. While calcium railgun is perfectly possible for incredibly light weight railgun design. While apparently some people has designed coilgun made out of amorphous carbon and...potassium out of all thing. After seeing (i forgot their name)'s railgun, I changed my railgun composition to Aluminium Copper Lithium. It requires thick rail and thus easier to aim and shot, but it yields high velocity and accuracy. As a rule of thumb, 'stay away from the enemy, or kill them before you flew into their range', the high command at AS love it. Smaller and non-ASF railguns still relies on VanChromeSteel/AmorphousC/AlZnMg as usual. I assure you potassium railgun is completely possible. Just look at NOF's crazy potassium railgun designs.  |

Calcium is still the most effective light weight railgun material for me.
For potassium, you need to increase its barrel width to ridiculous level and make it heavier anyway.

Same for the 1GW reactors. I didn't add the radiation shielding (as I usually don't use it on the reactor itself) but if you want to add it the reactor is still cheaper than the existing reactor design with an equivalent level of radiation shielding to match the hazard level.

jasonvance I think you need to double-check your numbers, because I can't get your 101 MW @2400k reactor working. It's running way hotter than it is in your image, so something weird is going on. EDIT: Okay, so no, you don't need to check your numbers, but apparently my game is starting to get weird because of all of the modded materials I've added into the game or something.

Eh, it's not crashing the game or anything, it just means I have to actually type in the code values when copying someone else's design. As far as I can tell, the problem goes away when I leave a design, delete it, then open up a new one, so it's not much of an issue. |

There are a few micro adjustments (beyond the visible rounded numbers) that are required like the neutron flux ratio is 1.969 not 1.97 (which is displayed at rounded up) |

Lawson, Amimai, erik have participated in ship competitions. Thorneel and Deskjester have published only components, IIRC.
